    We’re constantly impressed with the ergonomics and safety Swift features like macros and key paths unlocks. I’m not aware of another SQL library out there that remains type-safe over the JSON data in a column 😁
    A side-by-side of StructuredQueries' JSON APIs with the SQL it generates from the quoted post's link.

    Take it from our personal experience: you do NOT want to throw “Sendable” on just any type!

    Sendability errors in Swift might make you wonder if you should be adding “Sendable” to all your types. It seems innocent enough, and don’t we want all our types to be concurrency-safe? The answer: an emphatic NO! Take great care making a type sendable 👇

    These tools really do feel like magic to work with. You describe your features and how they should work, and you get an incredible feedback loop (for human or agent alike!) to something that just works.

    And all of TCA’s powerful testing tools just work! You play a script of user actions to your feature and get to exhaustively test how your feature changes over time by describing it in simple mutations:

    It’s not possible in a generic/static way, but you can run an actor on a specific actor dynamically at runtime by overriding its unowned serial executor. One of the many things we cover in our videos!
